BICEPS_CURLER_COUNTER

The BICEPS_CURLER_COUNTER is a fitness tool designed to help gym enthusiasts estimate their biceps curling pose and track the number of repetitions (reps) they are performing. By analyzing the angle of the bicep during the curling motion, the system accurately counts the reps in real-time through a camera feed or video input.

Installation

1. Clone the repository:

   git clone https://github.com/codeflamer/POSE-ESTIMATION.git
   cd POSE-ESTIMATION/BICEPS CURLER APP

2. Install the required dependencies: It is preferabele to run in a virtual environment making use of environments like conda or venv.

   Requirements:

   • protobuf
   • mediapipe
   • opencv-python
   • numpy

   pip install protobuf==4.25.5 mediapipe opencv-python numpy

Usage

After installing the required libraries, you can run the program to start counting bicep curl repetitions from a camera feed or video.

jupyter notebook

You can run this from the command line and execute the cells in the BICEPS_CURLER_COUNTER.ipnb

The application will track your bicep curls and display the current count of repetitions based on your pose.

Keypoints for Angle Calculation

In order to correctly estimate the number of repetitions, the system uses MediaPipe to detect keypoints on the body, particularly focusing on the elbow, shoulder, and wrist. These keypoints are crucial for measuring the angle of the bicep during a curl.

To measure the angle of the bicep:

• The angle is calculated using the elbow as the vertex and the shoulder and wrist as the defining points.

This angle is then used to determine the stage of the curl, which in turn tracks the reps:

if angle > 140:
    stage = "down"
if angle < 45 and stage == "down":
    counter += 1
    stage = "up"

Tracking Reps

The system follows the below logic for counting repetitions:

1. Down Stage: If the arm is fully extended, with the elbow angle greater than 140 degrees, the stage is set to "down."
2. Up Stage: As the bicep contracts and the elbow angle decreases below 45 degrees, a rep is counted, and the stage is updated to "up."

The cycle repeats to accurately count each bicep curl during the exercise.

Results

Here’s an example of the output from the system, where the biceps curl repetitions are counted in real-time from a camera feed:

The current rep count and stage (up or down) are displayed on the video feed for real-time feedback.
